Spatial Vision in Band-Winged Grasshoppers (Orthoptera: Acrididae: Oedipodinae)
Spatial vision in band-winged grasshoppers (Orthoptera: Acrididae: Oedipodinae) A Senior Thesis Presented to the Faculty of the Department of Organismal Biology and Ecology, Colorado College By Alexander B. Duncan Bachelor of Arts Degree in Organismal Biology and Ecology May, 2017 Approved by: _________________________________________ Dr. Nicholas Brandley Primary Thesis Advisor ________________________________________ Dr. Emilie Gray Secondary Thesis Advisor ABSTRACT Visual acuity, the ability to resolve fine spatial details, can vary dramatically between and within insect species. Body-size, sex, behavior, and ecological niche are all factors that may influence an insect’s acuity. Band-winged grasshoppers (Oedipodinae) are a subfamily of grasshoppers characterized by their colorfully patterned hindwings. Although researchers have anecdotally suggested that this color pattern may attract mates, few studies have examined the visual acuity of these animals, and none have examined its implications on intraspecific signaling. Here, we compare the visual acuity of three bandwing species: Dissosteira carolina, Arphia pseudonietana, and Spharagemon equale. To measure acuity in these species we used a modified radius of curvature estimation (RCE) technique. Visual acuity was significantly coarser 1) in males compared to females, 2) parallel to the horizon compared to the perpendicular, and 3) in S. equale compared to other bandwings. Unlike many insect families, body size within a species did not correlate with visual acuity. To examine the functional implications of these results, we modeled the appearance of different bandwing patterns to conspecifics. These results suggest that hind- wing patterning could only be used as a signal to conspecifics at short distances (<50cm). This study furthers the exploration of behavior and the evolution of visual systems in bandwings. -
SEVEN PREVIOUSLY UNDOCUMENTED ORTHOPTERAN SPECIES in LUNA COUNTY, NEW MEXICO Niccole D
International Journal of Science, Environment ISSN 2278-3687 (O) and Technology, Vol. 10, No 4, 2021, 105 – 115 2277-663X (P) SEVEN PREVIOUSLY UNDOCUMENTED ORTHOPTERAN SPECIES IN LUNA COUNTY, NEW MEXICO Niccole D. Rech1*, Brianda Alirez2 and Lauren Paulk2 1Western New Mexico University, Deming, New Mexico 2Early College High School, Deming, New Mexico E-mail: [email protected] (*Corresponding Author) Abstract: The Chihuahua Desert is the largest hot desert (BWh) in North America. Orthopterans are an integral part of desert ecosystems. They include grasshoppers, katydids and crickets. A large section of the Northern Chihuahua Desert is in Luna County, New Mexico. There is a dearth of information on the Orthopterans in this area. Between May and October of 2020, sixty adult grasshoppers, two katydids and one camel cricket were captured from a 5-hectare (ha) area at base of the Florida Mountains, which is the extreme southern portion of Luna County. Luna County was in a severe drought during 2020. The insects were identified using several taxonomic keys (Cigliano, Braun, Eades & Otte, 2018; Guala & Doring, 2019; Triplehorn & Johnson, 2005; Richman, Lightfoot, Sutherland & Fergurson, 1993, Otte, 1984, 1981; Tinkham, 1944). A previous New Mexico State University (NMSU) survey from 1993 had only documented grasshoppers in the Acrididae and Romaleidae families. The objective of this continuing study is to identify and document all species of Orthopterans found in Luna County, and correlate the populations with changing weather patterns. In this portion of the study, the majority of Orthopterans captured were Leprus wheeleri (Thomas), a previously documented specie. However, seven undocumented species were also captured. -

Animal Spot Animal Spot uses intriguing specimens from Cincinnati Museum Center’s collections to teach children how each animal is unique to its environment. Touch a cast of an elephant’s skull, feel a real dinosaur fossil, finish a three-layer fish puzzle, observe live fish and use interactives to explore how animals move, “dress” and eat. Case 1: Modes of Balance and Movement (Case design: horse legs in boots) Animals walk, run, jump, fly, and/or slither to their destination. Animals use many different parts of their bodies to help them move. The animals in this case are: • Blue Jay (Cyanocitta cristata) • Grasshopper (Shistocerca americana) • Locust (Dissosteira carolina) • Broad-wing damselfly (Family: Calopterygidae) • King Rail (Rallus elegans) • Eastern Mole (Scalopus aquaticus) • Brown trout (Salmo trutta) • Gila monster (Heloderma suspectum) • Damselfly (Agriocnemis pygmaea) • Pufferfish (Family: Tetraodontidae) • Bullfrog (Rona catesbrana) • Cicada (Family: Cicadidae) • Moths and Butterflies (Order: Lepidoptera) • Sea slugs (Order: Chepalaspidea) • Koala (Phascolarctos cinereus) • Fox Squirrel (Sciurus niger) • Giant Millipede (Subspecies: Lules) Case 2: Endo/Exoskeleton (Case design: Surrounded by bones) There are many different kinds of skeletons; some inside the body and others outside. The animals with skeletons on the inside have endoskeletons. Those animals that have skeletons on the outside have exoskeletons.

Box 250 Pierre, SD 57501-0250 611416 West Hidalgo Tolleson, AZ 85353 1 Abstract Strategies that utilize lower than traditional doses of insecticides in combination with swaths of applied insecticide that leave untreated areas between each swath are one way to significantly reduce the cost of controlling grasshoppers on rangeland. By leaving untreated areas, this strategy provides reserves for naturally occurring biological control agents and facilitates an economical integrated management approach for dealing with damaging populations of grasshoppers on rangeland. This three year study was conducted in different locations and years to develop and demonstrate on a large scale operational level, the utility of reduced area / agent treatments (RAATs) for significantly reducing costs to manage damaging populations of grasshoppers. In 1997 these reduced agent/area treatments (RAATs) resulted in about 15% lower mortality than traditional treatments while reducing pesticide use and cost by 60% with malathion and 75% with carbaryl. -

Invertebrate Distribution and Diversity Assessment at the U. S. Army Pinon Canyon Maneuver Site A report to the U. S. Army and U. S. Fish and Wildlife Service G. J. Michels, Jr., J. L. Newton, H. L. Lindon, and J. A. Brazille Texas AgriLife Research 2301 Experiment Station Road Bushland, TX 79012 2008 Report Introductory Notes The invertebrate survey in 2008 presented an interesting challenge. Extremely dry conditions prevailed throughout most of the adult activity period for the invertebrates and grass fires occurred several times throughout the summer. By visual assessment, plant resources were scarce compared to last year, with few green plants and almost no flowering plants. Eight habitats and nine sites continued to be sampled in 2008. The Ponderosa pine/ yellow indiangrass site was removed from the study after the low numbers of species and individuals collected there in 2007. All other sites from the 2007 survey were included in the 2008 survey. We also discontinued the collection of Coccinellidae in the 2008 survey, as only 98 individuals from four species were collected in 2007. Pitfall and malaise trapping were continued in the same way as the 2007 survey. Sweep net sampling was discontinued to allow time for Asilidae and Orthoptera timed surveys consisting of direct collection of individuals with a net. These surveys were conducted in the same way as the time constrained butterfly (Papilionidea and Hesperoidea) surveys, with 15-minute intervals for each taxanomic group. This was sucessful when individuals were present, but the dry summer made it difficult to assess the utility of these techniques because of overall low abundance of insects. -

Despite the importance of invertebrates in grassland ecosystems, few studies have examined how grassland invertebrates have been impacted by disturbances in the southwestern United States. These grasslands may be particularly sensitive to one common disturbance, livestock grazing, because they have not recently evolved in the presence of large herds of bison, an important mammalian herbivore. This study examined how livestock grazing influenced vegetation- associated insect communities in southeastern Arizona. Insect abundance, richness, diversity, community composition, and key environmental variables were compared between sites on active cattle ranches and sites on a 3160 ha sanctuary that has not been grazed by cattle for over 25 years. Vegetation-associated insect communities were found to be sensitive to livestock grazing. Overall abundance of these insects was lower on grazed grasslands, and certain insect orders appeared to be negatively affected by livestock grazing; beetles were less rich, flies were less diverse, and Hymenoptera were less rich and diverse on grazed sites. -
